Hickory nuts, also called Carya species, are a type of North American nut that is known for its sweet, nutty taste. These nuts grow in deciduous forests and woodlands and are often used in cooking and baking. They are also enjoyed as a snack food.
While hickory nuts are generally considered safe to eat, there is a small percentage of hickory nuts that are poisonous. The poison found in hickory nuts is called caryatoxin, and it is produced by a mold called Aspergillus flavus that grows on the nuts.

Symptoms Of Poisoning
If hickory nuts containing caryatoxin are ingested, symptoms of poisoning can occur. These symptoms may include nausea, vomiting, diarrhea, abdominal pain, and headache. In severe cases, symptoms of poisoning may also include liver damage, kidney damage, and even death.
It is important to seek medical attention immediately if you experience any of these symptoms after consuming hickory nuts. The severity of the symptoms will depend on the amount of caryatoxin ingested and the overall health of the individual.
In severe cases, hospitalization may be necessary to treat the symptoms of poisoning.
Identifying Poisonous Hickory Nuts
It is important to note that not all hickory nuts are poisonous. The majority of hickory nuts are safe to eat and do not contain caryatoxin. However, it is possible to identify hickory nuts that are poisonous by looking for certain signs.
One way to identify poisonous hickory nuts is to look for a green or yellow mold growing on the nut. This mold is called Aspergillus flavus, and it is the source of the caryatoxin found in poisonous hickory nuts. If you see this mold growing on a hickory nut, it is best to avoid eating it.
Another way to identify poisonous hickory nuts is to look for a rancid or musty smell. Hickory nuts that are poisonous may have a distinctive smell that is different from normal hickory nuts. If a hickory nut has a rancid or musty smell, it is best to avoid eating it.
It is also important to note that hickory nuts that are old or damaged may be more likely to contain caryatoxin. If a hickory nut is cracked or has visible signs of damage, it is best to avoid eating it.
Precautions When Eating Hickory Nuts
If you are planning to eat hickory nuts, it is important to take precautions to ensure that you are not consuming poisonous nuts. Here are a few precautions you can take when eating hickory nuts:
- Only eat hickory nuts that are fresh and not damaged.
- Avoid hickory nuts that have visible signs of mold or a rancid or musty smell.
- Wash hickory nuts before eating them to remove any dirt or debris.
- If you are unsure about the safety of a hickory nut, it is best to avoid eating it.
Conclusion
In conclusion, while hickory nuts are generally safe to eat, a small percentage of hickory nuts are poisonous due to the presence of caryatoxin. If hickory nuts containing caryatoxin are ingested, symptoms of poisoning can occur, including nausea, vomiting, diarrhea, abdominal pain, and headache.
